The current valuation for Tesla defies reason. I wouldn’t expect it to last. Despite its recent performance, I still don’t buy that it is worth more than the next ten largest automakers combined.
The valuations provided are generally based on a number assumptions (discount rates made up on government bond yields, beta and business risk, economics, growth rates, demographics, multiples etc.). They are logical and better than the blind guesswork/past observation that drives most retail investment. But assumption quality is potentially an issue. Even decent assumptions are subject to events beyond control or possible observation (covid).
Banks do it for personal gain to the extent that the research is sold to firms that want market information and analysts estimates for a given security. There are strict rules in place to prevent collusion, although for equity analysts collusion risk is normally seen between the analyst and the company being rated.
